1.1 Noise emission
Explanation concerning the measured noise level:
The sound pressure level is measured around the pump according to DIN
45635. The distance to the pump is I = 1 m.
The acoustic capacity reflects the total emission of noise by the pump. This is a
comparable value which does not depend on for example the distance to the
pump. The value is given according to the European directive 2000/14/EG. The
acoustic capacity is calculated from the measured sound pressure level.
Since both the acoustic capacity and the sound pressure level are expressed in
the same standard units one must be careful not to confuse the two values.

Safety
This Operating Manual contains basic instructions, which must be observed du-
ring mounting, operation and maintenance. Therefore the Operation Manual
should be carefully read before installation and start-up by the person in charge
of the installation as well as by all other technical personnel/operators and
should at all times be available at the installation site.
It is important that not only all general safety measures appearing under the
above heading “Safety” should be adhered to but also all other, specialized
safety instructions appearing under the other headings, e.g. for private use.
2.1 Symbols for Safety Instructions in the Operating Manual
All safety warnings contained in the Operating Manual which, when ignored,
may constitute danger for humans, are specially marked with general danger
symbols:
Safety symbol according to DIN 4844 - W 9
In case of electrical hazards they
are specially marked with:
Safety symbol according to DIN 4844 – W8
For safety warning which, when ignored may constitute a hazard for the machi-
ne and its functions as well as for the surrounding, the word
is added.
Symbols directly attached to the machine like e.g.
– arrow denoting the direction of rotation
– symbol for fluid connections
must be heeded and kept fully legible at all times.
